The execution, delivery and performance by the Buyer of this Agreement and each of the other Transaction Documents to which it is a party and the consummation by the Buyer of the transactions contemplated hereby and thereby do not and will not (1) conflict with or violate any provisions of the Agreement of Limited Partnership of the Buyer, as amended, or otherwise result in a violation of the organizational documents of the Buyer, (2)

conflict with, or constitute a default (or an event that with notice or lapse of time or both would result in a default) under, result in the creation of any Lien upon any of the properties or assets of the Buyer or give to others any rights of termination, amendment, acceleration or cancellation (with or without notice, lapse of time or both) of, any Material Contract of the Buyer, or (3) subject to the Required Approvals, conflict with or result in a violation of any law, rule, regulation, order, judgment, injunction, decree or other restriction of any court or governmental authority to which the Buyer is subject (including federal and state securities laws, assuming the correctness of the representations and warranties made by the Company and the Seller herein), or by which any property or asset of the Buyer is bound or affected, except in the case of clauses (2) and (3) such as would not, individually or in the aggregate, have, or would reasonably be expected to result in, a Buyer Material Adverse Effect.

(c) Investment Intent. The Buyer understands that the OP Units are “restricted securities” and have not been, and will not be, registered for issuance and sale under the Securities Act or any applicable state securities law, and the Buyer is acquiring the OP Units as principal for its own account and not with a view to, or for distributing or reselling such OP Units or any part thereof in violation of the Securities Act or any applicable state securities laws; provided, however, that by making the representations herein, the Buyer does not agree to hold any of the OP Units for any minimum period of time. The Buyer is acquiring the OP Units hereunder in the ordinary course of its business.

such additional information that the Seller and the Company possess or can acquire without unreasonable effort or expense that is necessary to make an informed investment decision with respect to the investment. Neither such inquiries nor any other investigation conducted by or on behalf of the Buyer or its representatives shall modify, amend or affect the Buyer’s right to rely on the truth, accuracy and completeness of the SEC Reports and the Seller’s and the Company’s representations and warranties contained in this Agreement.

(h) Brokers and Finders. No Person will have, as a result of this Agreement or any other Transaction Document or the transactions contemplated hereby or thereby, any valid right, interest or claim against or upon the Company, the Seller or the Buyer for any commissions, fees or expenses or other compensation, provided that the Buyer will pay reasonable financial advisor fees to JMP Securities LLC in connection with any Purchase Date.

(i) Independent Investment Decision. The Buyer has independently evaluated the merits of its decision to purchase OP Units pursuant to this Agreement and the other Transaction Documents. The Buyer understands that nothing in this Agreement or any other materials presented by or on behalf of the Seller or the Company to the Buyer in connection with the purchase of the OP Units constitutes legal, tax or investment advice. The Buyer has consulted such legal, tax and investment advisors as it, in its sole discretion, has deemed necessary or appropriate in connection with its purchase of the OP Units.

(j) Reliance on Exemptions. The Buyer understands that the OP Units are being offered and sold to it in reliance on specific exemptions from the registration requirements of federal and state securities laws and that the Seller is relying in part upon the truth and accuracy of, and the Buyer’s compliance with, the representations, warranties, agreements, acknowledgements and understandings of the Buyer set forth herein in order to determine the availability of such exemptions and the eligibility of the Buyer to acquire the OP Units.

(k) No Governmental Review. The Buyer understands that no federal or state agency or any other government or governmental agency has passed on or made any recommendation or endorsement of the OP Units or the fairness or suitability of the investment in the OP Units, nor have such authorities passed upon or endorsed the merits of the Offering.

(l) Residency. The Buyer’s office in which its investment decision with respect to the OP Units was made is located in Texas.
